The airbase (EHDL) I fly from has a CTR with neighbouring sectors. It's my home field and I don't need the airspace messages. There are so many messages it keeps blocking my thermal help. The ACK button does not seem to help.
Could you add a Pause/Silence/Snooze button as an overlay to snooze the messages like 15 minutes or so? Other ways I can think of is to disable all the airspaces before the start, but I have to do that every flight. Or I have to go in the airspace file and change the class from D to F or G. F and G airspace I have turned off messages for.
I did find the "airspace changes - persistent" option, so I can disable the appropriate airspaces one time. There's also the option to cycle the airspace from the Config menu, but you have to click it like 5 times to get the "airspace - all off" option. I would still be great to toggle the airspace with one button quickly during flight.
